Living in a damp and moldy house can contribute to depression independently of other personal and housing characteristics.

Based on a study of almost 6,000 adults living in eight European cities, researchers found that dampness and mold in a home is associated with elevated risk of depression. This heightened risk seemed to be due to both a perceived lack of control over the housing environment and physical health problems that are likely to be related to mold exposure.

The study's authors said their findings underscore "the importance of housing conditions as determinants of mental health and the importance of housing as a medium for universal health promotion efforts." They suggested more study into the issue to determine if the increased risk for depression was directly related to moldy and damp surroundings.
